Face3d
======
.. module:: ezdxf.entities
:noindex:
The 3DFACE entity (`DXF Reference`_) is real 3D solid filled triangle or quadrilateral.
Access vertices by name (:code:`entity.dxf.vtx0 = (1.7, 2.3)`) or by index
(:code:`entity[0] = (1.7, 2.3)`).
Unlike the entities :class:`Solid` and :class:`Trace`, the vertices of
:class:`Face3d` have the expected vertex order:
.. code-block:: Python
msp.add_3dface([(0, 0), (10, 0), (10, 10), (0, 10)])
.. image:: gfx/3dface.png
:align: center
======================== ==========================================
Subclass of :class:`ezdxf.entities.DXFGraphic`
DXF type ``'3DFACE'``
Factory function :meth:`ezdxf.layouts.BaseLayout.add_3dface`
Inherited DXF attributes :ref:`Common graphical DXF attributes`
======================== ==========================================
.. warning::
Do not instantiate entity classes by yourself - always use the provided
factory functions!
.. class:: Face3d
The class name is :class:`Face3d` because :class:`3dface` is not a valid
Python class name.
.. attribute:: dxf.vtx0
Location of 1. vertex (3D Point in :ref:`WCS`)
.. attribute:: dxf.vtx1
Location of 2. vertex (3D Point in :ref:`WCS`)
.. attribute:: dxf.vtx2
Location of 3. vertex (3D Point in :ref:`WCS`)
.. attribute:: dxf.vtx3
Location of 4. vertex (3D Point in :ref:`WCS`)
.. attribute:: dxf.invisible_edges
invisible edge flag (int, default=0)
=== ==============================
1 first edge is invisible
2 second edge is invisible
4 third edge is invisible
8 fourth edge is invisible
=== ==============================
Combine values by adding them, e.g. 1+4 = first and third edge is invisible.
